Workaround:
1. Go to the location where you have installed the Stat desktop client, the default location is the following:
C:\Program Files\Quest Software\Stat 6.3.0
2. Backup the original stcsr1.pbd and replace with the one that we have attached on this ticket.
3. Also, you should disable "Status Transfer Override" user right. Without this right, user won't be able to select CSR Status.
4. If open, log off from Stat client and log back in.
P.S: If you have "CSR Workflow - Change" user right disable, you might also want to enable it again.
